I have been trying all afternoon to bleed the brakes on my Caterham all afternoon. I have had some work done on the front end that meant that the front calipers had to be removed. They are Hi-Spec 4 pot calipers and were new last winter. I have also had new front brake hoses made and these are fitted. While I had the car on axle stands, I took out the rear brake pads to check them and clean and grease the sliders. Today, I thought I would try to bleed them. I have bled them at least 4 times this afternoon using over a litre of new brake fluid. I started with the nearside rear then offside rear followed by nearside front and lastly, offside front. I have done them each time until no bubbles are present, but when I press the pedal, there is nothing there. The pedal goes straight to the floor. If it helps with answers, I am using an "Eazi Bleed" system. I have also done both inner and outer bleed nipples on the front calipers. Stuart
